Just this morning, the 9th of May, I followed a few HCI schoolmates and headed to MacRitchie Resevoir for a Science Trail at Mac Ritchie resevoir. The purpose of the field trip was to educate us students abour more on ecology, and this is also a part of the MOE's plan to improve the learning trails that we have. The teacher in charge was Ms Sandra Tan, and my class, 2i3 had set off once we were gathered up in the resevoir. We were previously given a logbook and a worksheet to complete in the science trail, so I felt this hands-on activity was extremely fun.
We started at the Amenities Centre, where we gathered at around 8am in the morning and thereafter we headed towards the area below the promenade. We could see the forest reserve opposite the promenade, and also the Band Stand, Lim Bo Seng Memorial and the Kayak Platform. It was like a small hill, so we could see quite a distance away. Then we moved towards a small jetty above the promenade. We looked at water samples from the reservoir and started evaluating the water quality. Ms Sandra Tan explained the smell, colour, turbidity (level of 'murkiness' of the water), pH value, temperature and checked if any oil pollution was present in the water. Everything was fine, the water had no smell, green and yellow algae in the water which is perfectly normal in waters in a catchment area, zero levels of turbidity, no oil pollution, 28.6 degrees Celsius and pH value of 5.
We walked along the dam and the lawn area and around the east end of the reservoir. We also realised the history of reservoirs in Singapore and also the human impact of the water here. We had to turn back a while later when we were on the boardwalk. There was not enough time to walk through the whole thing and we had to go home. Back at the Amenities Centre, we were given a quick debrief followed by Ms Tan going through a few answers to the worksgeet. After that, I headed back home by bus. It was an unforgettable experience which I truly enjoyed.
